Posted below, I have some pics of my plants I believe I’m having issues with.
-Light: Mars Hydro TS3000
-4x4 Tent
-3 Gal Fabric Pots
-AC Infinity Fan/Filter Combo 6”
-AC Infinity Controller 67
-Distilled Water PH 6-6.5
-Was Using Advanced Nutrients but found out the ones I bought were for Hydro 🤷🏽♂️🤦🏽♂️
Just switched over to Fox Farm Trio and also got some Cal-Mag
Would love any help and input available. THANKS

Wood ash would be almost immediately available as a source of Potassium. It does raise PH #'s so be cautious. Bio-Char is always a good amendment for anyone gardening with bacteria/fungi (Inoculants). If lime, it would have to be a very expensive form of soluble lime. I work in Commercial Ag, it's not a cheap option for a small scale problem. What you may want to do in the future is add an amendment that will act as a PH "Buffer". This will "lessen the waves you make in the pool when a change is made", so to speak. . .
FYI: If using wood ash, it should be black hardwood ash. NOT from your charcoal grill (unless you use nothing except hardwood lump)!!
Charcoal brickets have binding agents and petro-chemicals in them that do not break down during combustion. Those ashes go in the trash. White hardwood ash is mostly devoid of nutes because most have oxidized off into the atmosphere.
Seeing a bit of calcium deficiency and maybe a bit of nitrogen, but otherwise they look pretty good. Start your new nutrient feeding and they should clear up in a couple of days.
In that first picture, the marking on the leaf in the background. Is that from light/wind stress?
Thanks. I believe it’s a Calcium and Nitrogen issue as well. I have been checking my runoff and it was crazy numbers.
PPM - Above 3500-4000
PH - Below 5, closer to 4.6
I havent added many nutrients.
Also I was regularly feeding Tea once a week but a Grower let me know not that much is needed Every week.
The plant in the 1st pick with the markings is I believe to be PH fluctuatio issue which I flushed with 6.2 pH distilled water with Cal Mag.
@GoldToothMike What soil are you in?
That PH is super low and the PPM is out there. Definitely have to get that under control. If they were mine, I would definitely start them on the nutrient schedule depending when you last gave them tea, and of course depending what soil you're in. Tea about once per week is fine if you have your PH and PPM numbers within range.
How many weeks are they?
Popped the seeds on Dec 15th. So 5 1/2 weeks.
Have a mix of Ocean Forest With more perlite added in as well as some light Warrior to lighten the medium a little.
I just flushed all today. So I’ll wait til at least Weds to start feeding.
But I don’t want to give it more food if them PPM runoff is so high.
At first I was not getting runoff so I believe that salts built up over time and I just have to get them out.
When I’m flushing, should I be with a ton of water or keep flushing until readings are correct?
If you're flushing to remove the build-up, I would flush completely and start from scratch. That way you can go from a clean slate and dial your numbers back in. FFOF does have nutes for apx 20 - 40 days, and for some reason it made your PH/PPM wonky, especially since you said you haven't really added any other nutrients.
Does anyone on this forum have experience with Light Warrior? Could it be a factor in throwing the PH/PPM off?
I flushed 3 of them really well. Got the ppm down to around 1000-1111 but the pH is staying at 5 with the runoff. Should it be the same coming out as going in?
@dpitas34 @mwhite9829 @Mr. Grow It This may require some more knowledge. I've heard about wood ash and lime to up PH runoff but I haven't experimented myself. These guys may have a solution on this one.
What PH meter are you using?
Your plants look good! I see a little magnesium deficiency coming on but that's about it. What dose of CalMag are you giving the plant and how often?
